I Have added a limited number of seamless (hopefully) pattern assets (30 in total) (import to asset Library) as a supplement to the Texture Paint Brushes:
https://forum.affinity.serif.com/index.php?/topic/55202-texture-paint-brushes-group-1-4-120480/
and as a working asset library for creating vector patterns. (Found these really useful while working on the on-going Inktober artwork Conversions )
Usage
1. The patterns can be complex inside the rectangular containers but they can be broken apart for other use. (Like spreading a texture inside another object/masking/ pattern making)
3. Tiled patterns (They should snap together)
4. Re-colouring (select internal groups in layer panel to re-colour collectively) [not 100% success can be a bit of trial and error!]
4. As symbols should you choose to add to symbol panel
Hope you find them useful!

Thought it was about time I added some of the brushes from a previous drawing completed in May ...Sorry it's taken so long!
Extended Brush set to 120 Mixed Patterns
Size restricted to initial Brush Size to 100px as not relevant to the patterning with these types of brushes.
Made some changes to the post:
1. Added A4 sample sheet for reference [PDF]
2. Added new sample sheets and removed old visuals from the post
